SPECIFICATION forming part of Letters Patent N0. 609,146, dated August16, 1898.

Application filed December 22, l89x7lv Serial No. 662,976. (No model.)

To @ZZ whom it may concern:

Be it known that I, HUBERT C. HART, a citi-` zen of the United States,residing at Union#` and bent into form, with an integral stud for theoperating-nut, thereby materially reducing the expense of manufactureand providing a simple and powerful wrench at a minimum cost.

i With this object in view the invention consists of certain features ofconstruction and combination of parts, which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure lis a side elevation of a Wrenchconstructed in accordance with my invention. Fig. 2 is a blank before itis bent into the form of a strap and jaw, and Fig. 3 is a view of theblank after it has been bent into the desired shape.

In said drawings, l denotes the handle of the wrench, having at one enda fixed jaw 2, and having on its under edge a series of teeth 3, cut inthe pitch of a screw.

et denotes the sliding jaw, 5 the strap, and 6 the pintle. These partsare stamped out of a piece of plate metal to the form shown in Fig. 2and then bent into the form shown in Fig. 3, thereby forming ajaw,-strap and pintle, the edges of the latter being iiled down to makethem round to receive the operatingscrew 7, which is held in place byupsetting the outer end of the pintle. The ends of the blank forming thejaw, after they have been folded to the position shown in Fig. 3, aresecured together by rivets S.

By constructing the jaw and the strap in the manner shown and describedit is evident that the cost of production will be greatly lessened, thusenabling the wrench to be placed upon the market at a greatly-reducedcost.`

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. As a new article of manufacture,a sliding jaw, strap, and pintle fora wrench stamped from a single piece, the blank being bent centrally ofits width to form the strap and then brought together and riveted toform the jaw and pintle, substantially as set forth.

2. A wrench consisting of a handle having a fixed jaw, and having teethof screw pitch on one of its edges, a sliding jaw and strap consistingof a piece of plate metal bentinto shape and riveted together andprovided with an integral pintle, and a screw swiveled upon said pintleand engaging the teeth of thehandle, substantially as set forth.V

In testimony whereof I hereunto aflix my signature in presence of twoWitnesses.
